Throughout Twitter's rebrand into X, advertisers have started becoming more confident using the platform, CEO Linda Yaccarino recently told CNBC. To bring more advertisers back, X has added new brand safety controls to stop ads from appearing where advertisers don't want them to appear. However, amid these improvements, at least two brands have once again suspended advertising on X, CNN reported—after a Media Matters report shared screenshots of their ads appearing next to posts from a verified pro-Nazi account.

According to CNN, the pharmaceutical company Gilead Sciences and NCTA-The Internet and Television Association "immediately paused their ad spending on X after CNN flagged their ads on the pro-Nazi account." This account—which was verified in April and has now been suspended—"shared content celebrating Hitler and the Nazi Party," with some posts garnering "hundreds of thousands of views," CNN reported.
